Each card: what it does, reported revenue, how it wins, and the one lesson to steal.
#01Aggregator
Snag · 免费赠送聚合
$30K/mo MRR*
Aggregates free-stuff listings. Built fast with AI, promoted through creator videos.
How it wins: sells "certainty of saving money" — the listings are free everywhere, reliability is the product.
Steal this: Sell certainty, not information.
#02Gamified tool
Posture Coach · 坐姿养虾
$17 one-time · $1K day one*
Real-time posture scoring; good posture levels up your pet shrimp.
How it wins: sells the mechanism that makes you do it, not posture knowledge everyone already has.
Steal this: Don't sell knowledge. Sell "getting it done."
#03Trust
trustmrr · 收入验证
$44K / 30 days*
Verifies income screenshots. Built with Cursor by Mark.
How it wins: turned "distrust" into a traffic entrance; monetizes via ad slots + 3% deal commission.
Steal this: Trust itself is a business.
#04Parenting
Napper · 宝宝睡眠预测
€47.99/yr subscription
Log sleep/wake; AI predicts the next nap and reshuffles the day's plan.
How it wins: UGC-style ads that mirror a parent's worst moment — "that's literally my life." Zero persuasion needed.
Steal this: Replicate the user's painful moment on camera.
#05Emotion
Remento · AI回忆录
$99/yr · $7M+ post-Shark-Tank*
Weekly question prompts → family records voice answers → AI writes the memoir → printed book with QR codes linking to the original audio.
How it wins: shrank "write a book for mom" into "answer one question a week." The QR + real voice sells fighting forgetting.
Steal this: Shrink big-hard into small-easy.
#06Viral consumer
Dreamface · 宠物唱歌
$29.99/yr · $800K+/mo*
Upload a pet photo, pick a song — the pet sings it.
How it wins: people won't share their own talking face; a singing pet is pure social currency. Same template × new photo = infinite content.
Steal this: The protagonist decides virality. Turn "watch" into "I want to try."
#07EdTech
Class Pet Garden · 班级宠物园
¥475K / single month*
Each student adopts a virtual pet; good behavior earns points that grow it. Built in 3–4 days with AI by a 05-born dropout who can't code.
How it wins: teachers are customers and the sales force — classroom videos are the most trusted ads. Sold on Xiaohongshu.
Steal this: Make the invisible visible (points → a living pet).
#08Photo AI
Halo AI · AI修图
$300K/mo in 45 days* · 1.2B views / 120 days
Describe an edit ("black suit"), get the photo. Saturated category.
How it wins: story-driven demos (koi fish photoshopped into a pot → prank dad) + 85 creators × one template. Even the loading screen carries the brand.
Steal this: Film product demos as stories. In a red ocean, the distribution format is the blue ocean.
#09Fintech fun
Rolling · 毒舌记账
1K → 100K users in 5 days*
Type "dinner ¥180" — it logs, categorizes, and roasts you ("feeding an army?"). Personality is switchable.
How it wins: in the most boring category, one joke is a nuke. Every roast screenshot is a free ad — usage is distribution.
Steal this: Tools solve problems; emotions create virality.
#10Dating
Plug AI · 暧昧消息教练
$80K/mo subscriptions*
Upload a chat screenshot, get reply suggestions for tricky romantic moments. Built by Blake while learning via ChatGPT.
How it wins: friends kept asking "how do I reply to this?" — repeated pleas are demand. Two $50 creators → 200K downloads in a week.
Steal this: What people repeatedly ask you is your product.
#11Fitness
Gravel · AI健身计划
$440K / single month*
Cloned Fitbot's model but fixed what was broken (exercise selection, progression). Tell it days + equipment, get sets/reps/weights.
How it wins: translated to Spanish, advertised in cheaper South American markets. Started at <$50/day ad spend.
Steal this: Copy the model, switch the market. Don't innovate — improve.
#12Emotion
no contact · 防找前任
$190K / 30 days* · ~6K active subs
Streak timer for not texting your ex + a fake chat box where AI talks you through the urge (messages never send).
How it wins: sells "those 5 minutes at 2am." Demand barely exists daily — it spikes. Peak moments pay more than daily needs.
Steal this: Don't find big needs. Find peak-pain moments, down to the minute.
#13Viral consumer
Facekit · AI脸打分
$100K / 2 months*
iPhone face scan → 3D model → symmetry/proportion report you can re-check over time. One 19-year-old ran 40 AI influencer accounts, 1,300 videos, 100M views.
How it wins: before/after is a viral format; "once you start studying yourself you can't stop" = retention. One person = a content team.
Steal this: Traffic skill is common. What's rare is your own product behind the traffic.
#14Photo AI
LensAI · 照片调光
$8K / 30 days* (headline said $50K)
Phone photo in → pro-looking lighting out. Nothing else.
How it wins: TikTok before/after carousels, same template, zero ad spend, 60M views. The change needs zero explanation.
Steal this: If it can't be understood in 3 seconds, it won't spread. Don't build big-complete; nail one visible change.
#15Productivity
Excel Formula AI · David
$23K/mo*
Type "sum orders over $1000" → copy-pasteable Excel formula. Built with Bubble + OpenAI, zero hand-written code.
How it wins: 97/3 freemium — 5 free/mo covers 97% (your sales team), 3% power users pay $6.99 (your profit). Survived a $5K/2-week API bill.
Steal this: Set free limits on day one. Free tiers are acquisition; they're also a cost firewall.
#16Geo arbitrage
Cal AI Hebrew Clone · Tomer
$81K / single month*
Saw US Cal AI at $1M/mo, built the missing Hebrew version in 2 weeks with Cursor. Localized food database, not just translation.
How it wins: information arbitrage (validated demand + unserved market) + revenue-share deals with local fitness influencers — which also filter out fakes.
Steal this: Opportunity lives at "validated × not-yet-covered."
#17Companion
Tolan · AI陪伴
$1M+/mo* · 100K+ subscribers
An alien friend with 25-tendon-grade memory: it remembers your interview and asks how it went the next day.
How it wins: memory = relationship. Traffic isn't tutorials — it's life scenes (cooking while asking how to cut a pumpkin: 18.7M views).
Steal this: Sell companionship, not intelligence. Put the product inside life, not inside a tutorial.
#18Jobs
Sprout · 右滑投简历
$250K/mo in 8 months*
Tinder-style job applications: swipe right, AI tailors your resume and cover letter per role. Built by Nicole in college.
How it wins: "whichever demo video wins, get more creators to copy it" — the creator matrix is an evolution lab, data is the referee.
Steal this: Matrix + evolution is the complete growth machine. Usage demos are the ads.
#19EdTech
Pingo · 毒舌口语陪练
$450–500K/mo*
Scenario-based speaking practice (ordering food, hotels) with instant correction — and a savage roast personality. Two college roommates.
How it wins: kills "speaking shame" (no scheduling, no embarrassment). Creators bait the AI into roasting them — personality is the content engine (52M views one video).
Steal this: Hide learning inside life scenarios.
#20Beauty
Glow Up · AI试妆
$800K / first year*
Screenshot a makeup look + your bare face → AI preview + product list + steps. Founder Louis failed 10 apps before this one.
How it wins: stopped guessing; mined TikTok beauty comments and built the exact sentence girls kept asking. Referral loop lives inside viral video comments.
Steal this: Turn a user's exact sentence into the product.
#21Party game
AI Undercover · 谁是卧底AI题库
$30–40K / 30 days* · 4,215 subs
Classic party game, unchanged rules — but AI generates infinite question banks (movies, anime, your group's inside jokes).
How it wins: didn't fix the game, fixed where it rots (repetitive questions). Free = the game; paid = infinity.
Steal this: Find what gets stale. Fill it with infinite AI.
#22Fitness
Symmetry AI · 肌肉分析
$200K/mo* · ~zero platform ads
Physique photo → which muscles are strongest/weakest → adaptive training plan + progress tracking. $14.99/mo.
How it wins: content acquires, product retains, payment data filters traffic — top 5 of 50 influencers beat the other 45 combined, measured per-creator.
Steal this: Views are vanity. Paying users are the referee.
#23Sports
3AK · AI跑姿分析
$10K+/mo*
Upload a running video → AI scores form, flags arm swing/stride → re-test after training. Built by two track students with zero coding background.
How it wins: the one-person-company stack — AI builds + domain expertise becomes the product + 150K existing fans become day-one users. $60→$30/yr tripled conversion.
Steal this: Domain experience is AI's last moat. Price for who actually pays.
#24Gamified tool
Cat on Chair · 番茄猫
$18K / 30 days* · ~$80K / 9 mo
A Pomodoro timer where a cat keeps you company: finish 25 min → gifts; quit early → trash on screen. 95% of code AI-assisted; all art by illustrator Sara.
How it wins: reward + shame + collection turned a close-after-use timer into a game. The $29.99 lifetime plan outsold subscriptions.
Steal this: AI executes; humans supply the soul. And: some users hate subscriptions — sell them "pay once."
#25Hardware
Physical Phones · 反智能手机座机
$800K / 6 months* · $120K presale in 3 days
A $100 retro handset that rings via Bluetooth when your phone rings. Pick up, talk — never touch the screen.
How it wins: content → presale → fund production with prepayments. Zero inventory, zero loans, zero investors. Sells "offline but reachable."
Steal this: Validate with content before you manufacture anything.
#26Utility
点个关 / Push-up Alarm · Early, 24
$50K / 28 days*
To dismiss the alarm: put the phone down, do push-ups on camera. Verified, then silence.
How it wins: reverse differentiation — everyone made alarms easier to dismiss; this one made it nearly impossible. Bloggers' morning vlogs demo it with zero explanation.
Steal this: In a red ocean, be opposite, not better. Opposite is memorable; better invites comparison.
#27Creative AI
Dog Vibe Coding · 狗做游戏
Fun case, not a money case
A dog steps on a Bluetooth keyboard; every 16 chars earn a treat. Rule: "treat every keystroke as a riddle from a genius game designer." Claude Code builds a playable game in 1–2 hours.
How it wins: the frame turns noise into signal. Constraints (16 chars, riddles only) focus the AI.
Steal this: Don't give AI infinite freedom — give it an interesting cage.
#28Dev tool · $80M exit
Base44 · 说话生成App
$80M Wix acquisition · ~$100M run-rate 9 mo later*
"Build me a CRM" → pages, database, auth, deployment. Solo founder, zero funding, 6 months to exit.
How it wins — the 3-layer flywheel: (1) fast delivery — sell results, not tools; (2) light acquisition — users' shared apps are the ads; (3) low cost — own model (Base1) took margins from ~0% toward 60%.
Steal this: The 3 questions: fast results? light acquisition? costs that scale down? Three yeses → all in.
#29Design AI
Recu · 会画过程的设计AI
20K users in weeks*
Describe your brand → logo + site + posters as one visual system — and it draws the design process (grids, alignment) live.
How it wins: AI products are evolving from "give answers" to "show the work." Process = trust. When everyone can generate, taste is the moat.
Steal this: In the AI era, compete on taste, not compute.
#30Design AI
Rikyū · MCP设计工具
Early stage
"Never think about design again." Call design from inside your AI coder (Claude/Codex/Cursor) via MCP; output lands straight in your project. From $5/mo.
How it wins: design-as-API. Opposite philosophy to Recu (hide the process vs. show it) — same need, both can live.
Steal this: For one need, opposite product philosophies can both win. Pick yours deliberately.
